Check Your Balance Due

You should refer to the notice you received for your latest balance due or have it handy and call our toll-free automated phone service for your current payoff amount. If you don’t have your notice, you can call 1-800-829-1040 to find out your current payoff amount. You can use our Get Transcript tool to request a Tax Account Transcript if you need to verify that payments you already made were applied to your tax account. Note: A transcript won’t provide you with a payoff amount.

Prevent Future Tax Liabilities

You can reduce or even eliminate a balance due after filing, by adjusting your withholding amount or making estimated payments.

The IRS Withholding Calculator can help you adjust the amount withheld from your pay by your employer, in order to reduce or eliminate your balance due.

Estimated tax is the method you use to pay tax on income that is not subject to withholding, such as self-employment income.
